SWITCH.

Application filed July 31, 1925. Serial No. 47,335).

This in tion relates to improvements in switchesl the general objectbeing to adapt the same for connection with a head post of a bed, theoccupant of the bed by his own weight will cause the switch to be openedand the light within the room extinguished or vice versa.

lith the above and other objects in view.l the invention furtherincludes the following` novel features and details of construction, tohe hereinafter more fully described, illustrated in the accompanyingdrawing' and pointed out in the appended claim.

ln the drawin;:- e

Figure 1 is a side elevation of my invenlion as applied and in use.

Figure 2 is a top plan view of my invcntion per se.

Figure 3 is an end elevation of my invention.

Referring' to the drawing in detail, wherein like characters ofreference denote correspending` parts, the reference character' 10indicates a base plate having its forward end terminating in an upwardlyextending offset end portion 11 while a pair of spaced parallelapertured ears 12 are arranged adjacent the opposite end of the baseplate 10, the purpose of which will be presently apparent. Positionedupon the upper side of the base plate and between the offset end portion11 and the apertured ears 12 carried thereby and rigidly secured theretois a base or block 13 preferably constructed of some dielectric materialand having positioned upon its upper side a. knife switch 14. Pivotallymounted as at 15 between the apertured ears 12 is the lower offset endportion 16 of an angulanlever 17 having shafts 18 including a lowerbifurcated end portion 19 received upon the upper side and pivotallysecured thereto and adapted for insertion within the usual andconventional form of sleeve 2O included within a bed post 21.

A. connectingg` arm 22 includes upper and lower bifurcated end portionsfor pivotal association with the annular lever 17 and outer free endportion of the knife switch lll while a, r .tractile spring; 23 has itsoppocnds connected to the upwardly extending): end portion 11 of thebase plate 10 and the upper and forward end of the angular lever 17whereby the said connecting arm 22 will normally hold the knife switch14 in a closed position. Binding` posts 24 are site arranged upon theupper side of the base or block 13 and connected to the knife switch111e, the source of current and the particular light to be illuminaterhnot shown.

ln the inode of operation of the present invention it is clearlyapparent and manifest that when the shaft 18 has been inserted withinthe sleeve 2O carried within a bed post 21 and preferably the headthereof7 the said switch per se is connected in circuit with the sourceof current and the light to be illuminated that the user of thisparticular switch has applied to his bed will of his own weight swingthe lower olfset end portion 1G of the angular lever 17 upon its pivot15 whereby the said connectingrod will be caused to be moved upwardlyand release the knife switch lll against the tension of the retractilespring 23 whereby the circuit will be opened and the light extin- `ojuished. A bell may be Connected in circuit with the switch mounted uponthe bed post whereby the occupant of the particular bed, susceptible tosleep walking will immediately be awakened upon leaving the bed by theringing of the bell. The invention may be used equally and eifectuallyas well to addicts of sleep walking in camps, in so far as the switchmay be mounted upon a camp cot by and connected in circuit with theautomobile horn button. It is to be noted that this invention will beexceedingly useful in lire departments, sich rooms, hospitals and thelike in so far as the lightmay 4be readily and easily thrown on upon theoccupant leaving his respective bed.

The invention is susceptible of various changes in its form, proportionsand minor details of construction, and the right is herein reserved tomalte such changes as properly fall within the scope ofthe appendedclaim. i

Havinsr described my invention what is claimed is:-

A device ofthe character described including a base plate having` oneend extending upwardly and perforated. spaced apertured ears extendingupwardly from opposite sides of the base aty the other end thereof, aninsulated block mounted upon the base plate and having one end arrangedagainst the upwardly extending end of the base., a knife switch mountedupon the insulated block, a substantially shaped lever having one armpivotally mounted between the spaced perforated ears and the other armeziendng above the knife Switch, a 'coil spring; having one end Connecedto the upvzudly exending; end of the buse plate und the other endudjustably connected to the second zum of the level', means formingoperative connection between the knife switch and the second :um of thelever, und n Weighted member having' pivotal conneeon with 'he Huet zumof the lever at a point adjacent the pvot point of the lever us and forthe purpose specified.

in nes'timony whereof u'x my signature.
